Brachycephaly is characterised by the skull width reaching more than 81 percent of the skull breadth. It developed relatively recently through various processes of brachycephalisation around the world. It is most common in Europe, Asia, and America, often, but not always in cold climate. In Africa it is sporadically found in some populations of the Congo forest, more rarely in savannahs (e.g. in Shari) as well as the interior of Madagascar. In Central and Eastern Europe brachycephaly dominates, just like in Turkey, Central Asia, and Korea. Brachycephaly is common in many valley and coastal populations of Indochina and the Sunda Islands as well as in East Polynesia. In America it is found in the natives of the Pacific forest, around the Caribbean, in Central America as well as the Andes and Patagonia.
